MACHINE.

SPECIFICATION forming part of Letters Patent No. 356,089, dated January 18, 1887. Application filed December 12, 1885. Serial No. 185,435. (No model.)

To all whom it may concern.-

, Be it known that I, GEORGE BEBE, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in carding-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for carding woolen and cotton fiber; and the object of my invention is to keep the doffer of the carding-machine free from dirt and shortfibers, which unavoidably accumulate in the wire card-clothing with which the circumference of the doffer is covered.

Heretofore it has been necessary to remove the accumulation by hand, as otherwise the dirt and short material wedge down into the wires until they become so filled up that the doffer is not able to receive the stock properly from the main cylinder. The result is that much of the stock falls to the floor and is U Wasted.

My invention is designed to work automatically and keep the doffer constantly clean, without interfering in any respect with the regular operations of the machine to which it is attached. The mechanism by which this is accomplished is illustrated in the accompanying drawings, in which Figure l is a side View of a portion of a carding-machine, showing my invention attached. Fig. 2 is a perspective view of my attachment without the carding-machine. Fig. 3 is an end view of a part of the doffer and of my cleaning device, showing the direction in which the wires in the card-clothing are inclined while in use on the doffer and on the stationary and vibrating bars of my cleaner. This figure shows the vibrating bar in dotted lines at the beginning of the vibration or stroke and in the act of cleaning the doffer,and the full lines show the bar at or near the end of stroke.

Similar letters refer to similar parts throughout the several views.

A is the card-frame, to which my mechanism is attached.

B is the doffer, and b the wire card-clothing to be cleaned by my attachment.

0 is a horizontal bar carrying a strip of wire card-clothing or similar material, 0, on

its under side; which acts as a comb. The bar is fixed rigidly to the shaft D by the arms d and braces d, and turns with the shaft.

E is a crank-arm keyed or otherwise fastened to the end of the shaft D, and carrying the crank-pin e at the outsideend of the arm.

F is the crank shaft or bar connecting the crank-pin e with a corresponding crank-pin, f, on the side of the pulley G. I

The pulley G is provided with a'radial slot, 9, by which the pinf can be adjusted to regulate the length of the stroke of the crank-bar. I fasten the pulley G in place by drilling holes in the frame at the proper height and bolting on a bracket having suitable bearings.

I get my power by fixing an extra pulley, H, to the shaft of the first worker, h, and running a belt from there to the pulley G; and to keep the belt from slipping off or interfering in any way with the crank-shaft F, I make a flange, 9, around the outside of the rim.

By the arrangement above described the horizontal bar 0 is given a uniform .vibratory motion.

The shaft D, to which the bar 0 is attached, is either straight with collars or journaled at each end in the boxes I, having adjustable bearings t in the vertically-adjustable brackets K. The brackets Kare each provided with two uprights made continuous with the bracket. The boxes I are placed between these uprights, and are held in place by the bearing-screws i, which pass from the outside through threaded holes in the uprights and press against the boxes I, thereby holding the boxes in place. The bearing-screws are long enough toallow of a horizontal adjustment of the boxes by tightening one screw and loosening the other. The brackets K are supported by the standards L, and are adjusted by means of the bolts k in the vertical slots l. The standards L have a horizontal adjustment by means of the slots Z in the feet L.

M are arms or brackets made continuous with the standards L, and projecting at right angles from the standard. Their purpose is to give support to the horizontal bar N.

mare slots for adjusting the position of the 7 bar N. The upper face of the horizontal bar N the stroke.

is covered with a strip of wire card-clothing, n, or similar material, acting as a comb whose teeth or wires slope out or away from the carding-machine, as shownin Fig. 3. The bar N is stationary while the machine. is in operation, and its position with relation to the vibrating bar 0 and of both with relation to the doffer B is such that during each vibration of the bar 0 the wires in the comb on the under side of the bar will pass through the wires 1) on the doffer at the beginning of the vibration or stroke, and through the wires n on the bar N at'the end of the samevibration. The. wires son the under side of the bar 0 slope outwardly, as shown in Fig. 3.

O is a trough or receptacle under the barN to catch and save the short stock combed from the doffer.

In practical operation the wire combs or brushes onthe under side of thevibrating bar 0 come in contact with the wire cover on the doffer, and on the downstroke of the bar, as shown in dotted lines in Fig. 3, the comb 0 passes between the wires on the doffer and combs out all of the dirt and adhering. fibers, and carries them with it past the brushes or comb on the stationary bar N to the end of On the return-stroke, however, the position of the wires on the two bars causes the wires 11. on the bar N to comb and brush out all of the dirt and adhering fibers, allowing them to drop into the receptacle 0. This constant brushing and combing operation keeps the wires on the doffer perfectly clean, and enables the doffer to do its allotted work systematically and perfectly, receiving the stock in regular quantities from the main cylinder, thereby preventing an over-accumulation of stockon the cylinder, and the consequent filling up of the main cylinderand waste of stock, and also obviates the necessity of cleaning the whole card so frequently as heretofore.

The object in taking my power from the shaft of the first worker, h, is because more of that pulley is exposed to the belt than with the others, and it is therefore less liable to slip.

It is obvious that I can connect my belt at any other point, or that I could get the motion by means of a system of gears instead of a belt. a

As doffers vary in size with the different styles of carding-machines, the slots and adjusting-bolts previously mentioned are necessary in adjusting the cleaning mechanism to the diameter of the doft'er.

It will be seen that the bar 0 at one end of its stroke comes in contact with the doffingcylinder and at the opposite end of its stroke with the clearing-bar N. The doffing-cylinden being continuously revolved by the driving mechanism, the different portions of its circumference are successively acted on by the bar 0, so that the said cylinder will be kept in the desired clean condition.

In operation the dotting-roller is revolved slightly faster than the swinging motion ofthe' stripper by means of suitable disposition of the driving mechanism. By thus causing the stripper to move slower than the surface of the doifer the former operates to partially clean the doffer during both its upward and downward stroke. Also, by reason of the relative speed described, the clothing of the stripper will enter gradually that of the roller until such stripper has reached the end of its upward stroke, thus easing the operation of the machine, and so avoiding any damage to the clothingof said parts, such as might occur if they were brought abruptly into contact. In the construction shown this relative speed is obtained by the belt gearing and size of parts, to which I will now refer in detail. The bar 0, it will be noticed, is supported a distance from its center of motion but slightly in excess of the semi-diameter of the pulley G, from which it receives its motion, and said pulley G is of equal size with the pulley H, from which it receives its motion through the medium of belt G, so that the bar 0 moves but slightly faster than the pulley H. On the shaft of the doffer I secure a pulley, P, as indicated in dotted lines, Fig. 1, and such pulley, and through it the doffer, is revolved by a belt, G guided by pulleys g and passing over the pulleys on the workers Q. This belt G is driven by a pulley, h, on the shaft of .pulley H, the said shaft of pulley H being the first one of the workers. The pulley h is geared by belt I? with thedrive-shaft P and such pulley h is usually made slightly smaller than the pulley H, as shown. The pulley P being less than half the size ofthe doffer-cylinder B, and running on the same shaft, it will readily be seen that the surface of the doffer moves faster than the bar 0. This gearing is simple, and'will be readily understood from Fig. 1 of the accompanying drawings.

Having thus fully described my invention, what I claim as new, and wish to secure by Letters Patent, is-

1. Theimproved dofi'er-cleaning attachment for carding-machines, consisting of the standards L, having slots Z, and provided with brackets M, having slots m, the brackets K,having bearings for the boxes I, bolts 7r, connecting brackets K with standards, and passed through slots Z, whereby said brackets K may be held at different points of standards L, the boxes I, the shaft D, journaled in said boxes and having arms d, the bar 0, supported on arms d, the bar N, and bolts connecting said bar with brackets M, and passed through the slots at thereof, substantially as set forth.
